[texts]BBC Research and Development Report Number 1980-02
R&D Report 1980-02 : Carfax': an example of an f.m. signal generated using digital techniques. P. Shelswell This report describes a method of generating frequency-modulated signals using digital techniques. The digital process introduces little distortion and provides a stable centre frequency. The drive for a "CARFAX" transmitter is described as an example of its application.

[texts]BBC Research and Development Report Number 1961-07
R&D Report 1961-07 : Crystal-diode modulators for the frequency range 10-1000 Mc/s. G.J. Phillips, R.G. Manton This report describes the development of low-power balanced diode modulators suitable for amplitude modulation by television or sound signals of a carrier in the frequency range 10-1000 Mc/s. From an original model, built in 1954, two later models have been developed having better performance in regard to the insertion loss at the carrier frequency, and uniformity of modulation response...

[texts]BBC Research and Development Report Number 1963-64
R&D Report 1963-64 : Line-store standards conversion: The subjective effect of certain switch and store imperfections V.G. Devereux The experiments described in this report were carried out in order to investigate the subjective effect of interference on a television display caused by variations in the transfer characteristics of the switches and storage devices in a line-store standards converter; these variations in the characteristics of switches and storage devices result in perturbations of...
